Students investigate the properties of two and three dimensional objects. In this geometry lesson, students differentiate polygons based on similarity and congruence. They make observation and interpret the data.

Students experiment with the luminosity of the Sun's light. In this luminosity lesson, students participate in an experiment with luminosity of the sun and flashlights. They make filters and fiber optic sources.

Eighth graders explore the Pythagorean Theorem.  In this middle school geometry lesson, 8th graders solve problems using the Pythagorean Theorem as they explore the definition of a theorem and attempt to determine the formula for...

Fourth graders practice multiplication and division with cooking recipes. In this math lesson, 4th graders look at a recipe and change it so that it works for twice as many people or half as many people. 

Students explore motor skills by participating in a drawing activity. In this hand coordination lesson, students utilize activity sheets in which they drag their pencil in a specific direction quickly and efficiently. Students utilize...

Students determine how land was divided and marked for boundaries in the early days of settlement in Delaware. Students mark out land on the playground according to the methods used by the early settlers. Students write a description of...

Seventh graders research on energy conversion. After they have researched several types of energy resources, teams of two to four create posters which depict how these resources can be conserved.

Learners develop a scaled down model of the solar system. In small groups, they calculate the scaled-down diameters of the planets and the sun, the scaled-down distance of the planets from the sun, complete two charts, and create a...

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Students create a scale model of a motor neuron that is two hundred times larger than the actual neuron. They identify the structures of a neuron and observe neurons under the microscope then use a worksheet to convert actual sizes into...

Eighth graders study how an embryo develops into a fetus by undergoing many physical changes which they observe on a poster. They examine the metamorphosis of fruit flies as they develop through a series of changes. They record the...

Studen collect trash around the community with trash bag and gloves. They recognize and describe ways that some materials

Pupils create a solar hot dog cooker. In this solar energy lesson, students use various materials such as tin foil and cardboard to build a hot dog cooker. Pupils cook their own hot dogs.

Students find math concepts in every day items. In this math concept lesson, students take ten photographs of things they find interesting. They analyze the photographs to find hidden math concepts such as counting, lines, angles,...

In this language arts review for grade 3 (3.2) instructional activity, 3rd graders answer 25 multiple choice questions in standardized test format about punctuation, parts of speech and grammar, with answer key.

Students design and build a solar concentrator. In this physics lesson, students evaluate their design and convince everyone why theirs is the best. They create a presentation and share it with the class.

Fifth graders explore the concept of area using the geometry of selected objects. The laboratory for this experience is the classroom. The lesson focuses upon the objects that have four sides like squares and rectangles.

Students make either and insect or a spider using materials their teacher provides. They then draw of picture of their organism and defend why it is either a spider or an insect.

Second graders, in groups, prepare a list of proposed record ideas for the class book.

Fifth graders explore the use of trigonometry to find unknown sides and angles in right-angled triangles, taking the concepts that were developed in the previous unit and looking at different ways of practicing the new skills. Students...

Students make observations about mealworms using hand lenses, rulers, and cotton swabs. Students complete their own mealworm observation chart, then they share their observations with the class. This is one station out of five in an...

Students classify rocks into groups after they observe the rocks and identify properties that can be used to divide them into groups. They then identify other properties that could be used to classify other objects into groups.

Students map an actual local waterway. They create full color scale drawings that include windfalls, plant cover, streambed composition, and landmarks such as trees, boulders, and slumps. This is a long-term project that involves...

Students will make a circuit on a mystery card. They will connect wires, bulbs, and battery to form an electrical tester. After students learn how to make one following the directions, they can create their own mystery card by...
